Abstract

This paper presents the finite element method for determining the stress intensity factors of steel plates
with different thickness having an elliptical cut-out in the center and subjected to different stresses. The
failure of the cracked parts affected by the stresses in the crack tip vicinity. The stress contribution can be
determined by the stress intensity factor K. For this purpose, an initial crack can be simulated and
modeled. Each of K corresponds to a crack propagation method. In this study the ANSYS software is used
for numerical modeling with several elements of solid type and nodes. a finer mesh is used around the
crack tip for more accurate results. Then an error percentage can be determined by using ANSYS results.
The present research is aimed to improve the formulation by including the effect of the crack-face closure
on the stress intensity factors K.
